Abstract

The composite analysis of the structure of anomalies of vertical motions revealed disturbances in the Walker and Hadley circulations in the whole tropical zone associated with the two types of El Nino. The Eastern Pacific El Nino is characterized by the suppressed convection over the Maritime Continent and by the intensification of ascending motions in the central and eastern Pacific. The Central Pacific El Nino is characterized by the double Walker circulation cell with ascending motions in the central Pacific and descending motions in the western and eastern Pacific. Significant differences in the pattern of vertical circulation anomalies outside the Pacific region are also found in the north and west of the Indian Ocean and in the area of South America and the Caribbean.
